SMD’s metal floor decking products are commonly used as part of a composite floor slab, where the decking acts as both permanent formwork and tensile reinforcement (sagging) in the bottom of the slab (basis of design in accordance with BS5950: Parts 4 & 6 or Eurocodes 3 and 4).
Alternatively, our decking profiles may be used as permanent formwork only. In this situation any reinforcement required to support the specified imposed loads is to be designed by the project structural engineer, ignoring any contribution from the metal decking.
All our profiles use steel strip in compliance with BS EN 10143 & BS EN 10346 with guaranteed minimum yield strengths of 350 and 450 N/mm2 and a minimum coating mass of 275g/m2.
